Just days before Dodge hopes to spin heads with the reveal of its Challenger Demon, muscle car tuner Hennessey has pulled the wraps off the amusingly named Exorcist, a Camaro ZL1 whose engine has been massaged in an effort to “cast out the demon.”

Actually, “massaged” might not be a strong enough word. By strapping a larger supercharger and intercooler on the ZL1’s LT4 V8, Hennessey has unleashed an extra 350(!) horsepower and 316 lb-ft of torque, for an even 1,000 hp and 966 lb-ft.

Those figures, say the tuner, are good enough to push the car from zero to 100 km/h in less than three seconds (the stock ZL1 does that in 3.5) and through the standing quarter mile in less than 10 seconds.

While you won’t see the Exorcist advertised by Chevrolet or its parent company, General Motors, Hennessey says the car can be ordered through a Chevrolet dealer. In the U.S., the upgrade runs $55,000 and includes a two-year, 24,000-mile (about 39,000 km) warranty.

And if your ZL1 has the optional 10-speed automatic transmission, it’ll need a $10,000 upgrade in order to handle the extra power.

If you’re keen on testing Hennessey’s 10-second promise, add the optional $9,000 drag package, which includes 20-inch wheels and drag radial tires, upgraded driveshaft, floor jack, and tool kit.

But Hennessey says the Exorcist is about more than just straight-line speed, and so it also offers a $7,000 road race package that brings lightweight wheels shod with Michelin Pilot Sport Cup 2 tires.
